I'm a huge fan of the feature folder approach to structuring ASP.NET Core applications. As you will probably already know, in the default application folder structure of a typical MVC application, we have separate directories for controllers, models, and views. As our application grows and we add more and more features, we spend a lot of time switching between these folders in our IDE or editor. It can also become quite difficult to quickly find the specific files we're looking for, particularly in the Models folder, as you'll usually have a handful of different view models per database entity.
An alternative approach is to group these controllers, models, and views into a folder per feature of the application. For example, the Features/Products directory would contain the ProductsController, right alongside the views and view models...
